LOCK.

SPECIFICATION forming part of Letters Patent' No. 712,078,V datedOctober, 28, 1902.

Application filed May 26, 1902. Serial No. 109,050. (No model.)

.To all wiz/0m t may con/cern:

Ee it known that I, CONRAD KUEBLER, a citizen of the United States,residing at Calamus, in the county of Clinton and State of Iowa,haveinvented a new and useful Lock, of which the followingisaspecification.

This invention relates to locks or latches such as are used mainly uponbarn doors, gates, and the like, and it has special reference to suchlookin g or latching devices which are used for locking .the gate ordoor to which they are applied in a closed position and also forsecuring them in an open position.

My present invention consists in certain improvements in the detailedconstruction of the latch whereby the locking-bolt when drawn backagainst the tension of its spring shall be engaged bya lever,whereby itshall be held in its withdrawn position, the construction of said leverbeing such that when the door is thrown either open or shut it shall beactuated to release the locking-bolt, causing the latter to-engage witha suitable keeper, and thus retain the door eitherin an open or closedposition. The detailed construction of the device whereby these objectsare attained will be hereinafter f ully described and particularlypointed out in the claims.

In the accompanying drawings, Figure-1 is a side vview showing myinvention applied to a door in position for operation. Fig. 2 is` ahorizontal sectional view,with dotted lines indicating the position ofaldoor and lock when the door is open, the bolt ofthe lock being shownin engagement with its keeper. Fig. 3 is a horizontal sectional Viewshowing Vthe bolt Withdrawn from the keeper and in engagement with thelever-catch or detent. Fig.'

4 is a transverse sectional view taken on the line 4 4 in Fig. 3.

Corresponding parts in all the gures are indicated by like characters ofreference.

The casing 5 of my improved lock may be struck up or formed from sheetmetal or castiron, and it is provided with fianges 6 to receive thescrews or fastening devices by means of which it is in practice securedin operative position. The casing 5 is provided with guides '7 and 8 forthe longitudinally-sliding bolt 9, the guide 8 being in the nature of aperforated partition, through which the said bolt extends, a spring 10being coiled upon said bolt between a shoulder 11 thereon and the saidpartition to force or shoot the bolt in an outward direction. The innerend of the bolt has; a transverse perforation 12, through which extendsa pin 13, which forms the handle by means of which the bolt ismanipulated. One end of said pin is provided with a detachable cap orthumb piece 14, interiorly threaded to engage with theexteriorly-threaded `end of the pin. The part of the said pin extendingthrough the perforation 12 in the bolt is of reduced diameter, thusforming a shoulder 15, which abuts against the side of the bolt andprevents the pin from being drawn entirely through. By this constructionthe pin may be withdrawn or detached from the bolt to enable it to bepassed through the slot 16, which must be formed for its accommodationin the door upon which the device is adj usted for operation. Thereduced end of the pin carrying the cap 14 extends through a slot 17 inthe casing 5. Theend of the pin 13 which projects through the slot 16 ofthe door is provided with an enlargement 18, by means of which it may bemanipulated.

The casing 5 is provided near its outer end with a slot 19, adjacent towhich lugs or ears 20 are formed for the passage of a pin or bolt 21,upon which the catch-lever or detent 22 is pivotally mounted. Said leveris provided near its outer end upon the side facing the bolt 9 with atooth 23, adapted to engage with.

a tooth 24, formed upon the opposing face of the bolt and serving torestrain the movement of said bolt in an outward direction under theimpulse of the coiled spring 10. The lever 22 is also provided closelyadjacent to its pivy otal point with a cam-shaped projection 25, adaptedto engage the opposing beveled face 'of the tube 24 'when the bolt 9 iswithdrawn against the tension of the spring. The outer end of the lever22 will thus be forced in the IOO end of the lever 22 forms a handle 27,which when the bolt is shot may lie in contact with the casing. When thebolt is withdrawn against the tension of the spring and the lever isactuated by the beveled tooth or projection 24 engaging the cam-shapedprojection 25 of said lever, the handle of the latter is moved outwardfrom the casing to the position shown in Fig. 3, the tooth 23 being thusthrown into engagementl with the notch at the outer end of the bolt andretaining the latter in its withdrawn position. It will be observed thatthe tooth 23 has been particularly described as being located near theouter end of the lever. This is important, because the extreme outer endof said lever must be free to engage the keeper of the bolt, as will hepresently described.

The keeper, which is designated by 29, consists ot' a hasp or staplesuitably secured to the door-framein a convenient position to be engagedby the bolt 9. A similar keeper 30 is secured to the wall or frame ofthe building in a suitable location to be engaged by the bolt when thedoor is thrown open.

The operation of my invention will be readily understood. The relativelocation of the parts when the dooris closed has been shown in Figs. land 2. lVhen it is desired to open the door, the bolt 9 is withdrawnagainst the tension ofthe spring by means of the pin or handle 13, thusdisengagingit from the keeper and at the same time actuating the lever22 by the beveled tooth 24 engaging the camshaped projection 25, thuscausing the tooth 23 to engage the outer end of the bolt and retain thelatter in its withdrawn position. Now in case the door is thrown wideopen the end or handle 27 of the lever will strike against the 'wall ofthe building, thus swinging the lever upon its pivot, releasing thetooth 23 from its engagement with the outer end of the bolt, causing thelatter to be shot by the spring l0 into engagement with the keeper 30,and thus securing the doorin an open position. If, on the other hand,the door be thrown shut, the extreme outer end of the lever 22 beyondthe tooth 23 will impinge upon the outer side of the keeper 29, thusreleasing the lever and causing the bolt to be shot intoengagement withthe keeper and securing the door in its closed position.

As will be seen from the foregoing description,my improved lockingdevice is simple in construction, easily operated, is capable of beingreversed or applied with equal facility to right as well as to left handdoors, it is not liable to get out of order, the operation of thelever-catch or detent is automatic, and said catch or detent isautomatically released, so as to cause the bolt to be shot when the dooris thrown either open or shut.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States l. rThe combination of a casing, thespring'- actuated bolt arranged slidingly therein and having a beveledtooth or projection, and a lever or catch facing said bolt and having atooth or projection adapted to engage the front end of the bolt,substantially as set forth.

2. The combination of the casing, the sliding spring-actuated bolthaving a beveled tooth and the lever provided on opposite sides ot' itsfulcrum with a cam-shaft projection adapted to "be engaged by saidbeveled tooth,

i and with a tooth adapted to engage the latter or the outer end of thebolt according to the position of the latter, substantially as setforth.

3. The combination of the casing, the sliding spring-actuated bolthaving a beveled tooth, the lever having a beveled projection on oneside of its fulcrum adapted to be engaged by said beveled tooth andprovided on the opposite side of its fulcrum with a tooth adapted toengage the outer end of the bolt or the tooth upon the latter, and akeeper adapted to receive the bolt and to engage the end of the leverprojecting beyond the tooth thereon, substantially as set forth.

4. The combination of the casing, the sliding spring-actuated bolthaving a beveled tooth, a lever having a cam-shaped projection adaptedto be engaged by the said beveled tooth and provided on the oppositeside of its fulcrum with a tooth adapted to engage the outer end of saidbolt or the tooth upon the latter, according to the position of saidbolt, and a handle formed by the inner end ot' the lever and adapted tolie in contact with the outside of the casing when the bolt is shut, andto be moved outward from the casing when the bolt is drawn,substantially as set forth.

5. The combination of the casing, the sliding spring-actuated bolthaving a beveled tooth, the lever provided on opposite sides of itsfulcrum with a cam-shaped projection and with a tooth, said tooth beinglocated at a distance from the outer end of the lever, a handle uponsaid lever lying outside the casing, keepers adapted to be engaged bythe bolt, and a handle for the latter, substantially as set forth.

6. The combination with a spring-actuated bolt, of a lever having meansfor engaging said bolt to retain itin adrawn position, said lever beingprovided with projecting parts on opposite sides of its fulcrum adaptedto engage fixed points of contact and thereby to release the bolt forengagement with a keeper, substantially as set forth.

7. The combination of a casing attached to a swinging bracket, aspring-actuated bolt within said casing, a lever having means forengaging said bolt to retain the same in a drawn position, said leverbeing provided with projections adapted to engage Xed points of contactand thereby to release the bolt for engagement with its keeper,substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
